Just wondering if the above 2 changes can impact performance in any case. I don't think they are related to this PR. These 2 changes are just making the value calculation more obvious for readability. Because we use the map size as threshold, we should multiply it by the load factor. There is no performance impact. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
